COLUMN-MOLD.

Specification of Letters Patent.

Patented Sept. 24, 1912.

To all whom it may concern:

Be it known that we, PHILIPPE A. DEs- LAURIERS and LOUIS P. DEsLAURIEns, citizens of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Column-Molds, of which the following is a specification.

Our invention relates to means for constructing concrete columns wherein a divided casing or mold is employed and consists particularly in improved means for securing and holding the mold in position for receiving the concrete.

To this end our invention consists in the.

features of construction and combination hereinafter described and claimed.

In the accompanying drawings forming part of this specification: Figure 1 is a perspective View of our invention, Fig. 2 1s a sect-ion on line iv-02 of Fig. 1, Figs. 3 and 4 are top and perspective views, respectively, of clamping means for holding the mold in position; Fig. 5 is a perspective view of a section of a mold illustrating our improved means for securing the same in position for receiving concrete. Fig. 6 is a top view of the same, Fig. 7 is a detail view of a part of the clamping means.

In the drawings the mold is shown made up of a main sheet 2 and an extension sheet 3, adjustably connected, and the whole bent into the shape of the column to be formed; the free edge 4 of the main sheet is bent outwardly and rearwardly as indicated best in Fig. 2, and a flange or iron 5 extends lon- ,gitudinally along the adjacent portion of the extension'plate 3 and is bent outwardly and formed at its outer edge with a lip 6, unrgierneath which the flange 4 is adapted to t.

For the purpose of holding the mold closed we provide templet frames each consisting of a split ring B, the ends 7 of the ring portions being bent outwardly and forms with openings 8 through which bolts 9 may be passed.

In Fig. 4 we show a clamping device for the ends 7 to be used in substitution for or in connection with the bolts 9. This clamping device consists of a plate 10 formed with parallel slots 11 inter-spaced to receive the ends]. The tongue 12 of the plate,

intermediate of the slots is rearwardly to allow the be drawn together after sition.

B represents a device for drawing the ends of the ring together as illustrated in Fig. 5. This consists of ahandle pivotally supporting at one end a block 13 formed with a pin 14, fitted to one of the openings 8, an arm 15 having pivotal support 16 atthe rear of said block and pivotallysupporting at its free end a block 17 corresponding to the block 13 and formed with a simllar pin.

In applying each templet frame adjacent ends 7 may be first secured together on the opposite sides of the flanges 4 and 5 as by the bolt 9, leaving the opposite ends of the ring unconnected. The device B is then employed with the pins 14 extending through the openings 8 in the free ends 7 and the handle of the device B turned to one side to draw together the free ends 7 of the ring; when drawn sufiiciently together the clamping plate 10 will be dropped over the ends 7 back to the blocks 13, as illustrated in Fig. 1, and the device B removed. The device B and the clamping plate 10 thus cooperate to allow the free ends of the templet frames to be drawn together and clamped in adjusted position.

By means of the features of construction shown and described we secure a mold which will be firmly clamped in position to receive the concrete entirely by means of the templet frames. Tightenim of the templet frames upon the mold will squeeze the flange 4.- within the angle iron 5,making a tight joint between said flange and angle iron and rendering unnecessary the use of any securing means passing therethrough.

We claim:

1. The combination with a split mold of the class described, one edge of said mold being turned outwardly and rearwardly with its edge interspaced from the mold, and a flange constructed to receive said bent edge arranged longitudinally along the opposite free edge of the mold, the edge of the mold carrying said flange underlapping said bent edge, the portion of said flange which overlaps the rearwa-rdly-bent edge being oiI-set preferably bent ends of the ring to the plate is in p0- with respect to the meeting edges of, themold, whereby a wedging action is produced at the joint, of means surrounding the mold for compressing said flange upon said bent edge.

2. The combination with a split sheetmetal mold of the class described having one of its edges outwardly and rearwardly directed, said edge being interspaced from the adjacent portion of the mold, and a flange carried by the'other edge of the mold and extending outwardly and forwardly over the rearwardly-directed edge, the edge of. the'mold carrying said flange underlapping said bent edge, the portion of said flange which overlaps the rearwardly-directed edge being oif-set with respect to the meeting edges of the mold, whereby a wedging action is produced at the joint, and means for clamping the rearwardly-directed edge within said flange comprising a templet frame surrounding said mold, said templet frame having outwardly-bent portions upon opposite sides of said flanges, means for contracting the templet frame, and means for holding the templet frame in contracted position upon the mold.

In testimony whereof we afiix our signatures in presence of two witnesses.
